The family of kidnapper James DiMaggio is asking the girl he abducted for a DNA sample so that they can determine whether DiMaggio was her father.

A spokesman for DiMaggio’s family told 10News.com that the family made the request after it was revealed that the DiMaggio left $112,000 to Hannah Anderson’s paternal grandmother, who he named as the sole beneficiary of his life insurance policy. DiMaggio died August 10 in a shootout with the FBI in a remote area of Idaho. Authorities believe he kidnapped 16-year-old Hannah after killing her mother, Christina Anderson, and 8-year-old brother, Ethan, at his house in Southern California.

“He expected the grandmother to take care of the two children with the money. He stated he did not want it to go to their parents because they were having marital problems and he didn’t trust them with the money on their own,” Andrew Spanswick told 10News.com.

Explaining the request for a paternity test, Spanswick said “We are requesting DNA samples from Hannah and anything they can get from Ethan. There are rumors Jim was the children’s real father. The parents didn’t marry until 2002. We think it’s strange he left them so much money with no explanation.” DiMaggio named Hannah’s grandmother, Bernice Anderson as the sole beneficiary in 2011, replacing his sister Lora Robinson.

Spanswick also described Hannah Anderson’s recent behavior as suspicious, saying, “Some things that Hannah is saying on her Facebook doesn’t add up so far; her latest posts are disturbing.” He did not elaborate.
